Currently i have a 1998 Ford f250 lightduty truck. It is a great truck but the 4x4 has been a problem and had some heater core problems and just am looking into upgrading. I'm looking into possibly buying a 07-08 Ford F250-350 or Chevy 2500hd single cab 4x4. I know the topic of gas verse has been worn out time after time but what would be better? Is diesel truck even realistic now with the price of diesel 40 cents more than gas to only get maybe 5mpg more? Also if i did go gas route Chevy 6.0 vs Triton 5.4 3v both good trucks but will get between 12-14 mpg. Which would you choose?
